VIDEO: Closing the gap with tactile probe accuracy

Paul Boughton

Following an intense R&D phase involving engineering from Nikon Japan, the LC15Dx is the first CMM laser scanner to benefit from a high quality Nikon lens and receive the Nikon branding.

LC15Dx accuracy comes close to the accuracy expected when using a CMM and tactile probe. Thanks to new solid state laser scanner technology, an innovative calibration method and high quality Nikon lens, the LC15Dx achieves a probing accuracy of 2.5μm (0.0001in) and a multi-stylus test accuracy of 6μm (0.00024in) in tests comparable to EN/10360-2 and -5.

A unique thermal stabiliser inside the scanner body eliminates the uncertainty and delay caused when the laser scanner is used before it has reached operating temperature. Probe tip compensation errors are also eliminated by using non-contact triangulation between the laser source, workpiece and CCD sensor to measure the surface of the workpiece directly.

The LC15Dx provides significant benefits for a wide variety of high precision parts and geometry, including small details, semi-rigid parts and the more demanding materials. A greater range and mix of surface materials, finishes, colors and transitions can be measured more efficiently without user interaction, manual tuning and part spraying.

Nikon Metrology’s unique third-generation Enhanced Scanner Performance (ESP3) technology maintains accuracy, speed and data quality by intelligently adapting the laser settings for each measured point in real-time.

Unwanted reflections are neutralised by an advanced software filter while changes in ambient light are absorbed by a high grade daylight filter.
